Application ied March 26, 1521. Serial No. 455,885.

/"oUM .1o/Low?I- 'it l71mg/ concern.' v Be it known that l, @Hannes Bangkirai; Steyr, a citizen of the United States. residin; at Gettysburg, in the county otlrPotter simplify and improve the construction and increase the utility and eiiieiencyo't devices of this character. M

Another object of the vide an apparatus oi this' ehara eter in which the straw orlike material ,is thrown do\\7n- `wardly upon theground and thus protected 'from the action ot the Wind.

Another object ot' tlieinveiitionlis to pro` vide an apparatus of this eliaraeterhaving means for adjusting the discharging inechanisin to adapt the feedto the condition or size of material. 5 Vllith these and other objects in View, the invention consists in certain novel features ot construction as hcreineifter showin` and. described and then specifically pointed yout in the claims, and in the drawingsillustrative ot the preferred einbodiinent ot the involition9 n i y y .l

-Tlie vehicle adapted to lieif'i'iig` dralt ani-k mals ottached thereto to' draw it over the tielth oi' any other suitable inoti've power may be employed. tor 'iispiiirpose "he're eeptacle is represented as cniiirising .a bottoni ineinher 10side nieiiihers'll and end and 13, the latter*preferably inclined as shown. j"` I Ther rear is represented at 1d, "the rear carrier Wheels et 15, thetorward axle invention is to ipro elevation yot thek rearl pork `,1vt"`1(5 Aand the .forward carrier Wheels 17.

The forward axle is provided fwiththe usual swivel device such as La iil'th Wheel 18 to envable the apparatus to be steered, and is likewise provided with a? draft appliance, represented conventionally at 19.

Bit its ends the' i'ioor10`is .torined with openings, and niouiited for' rotation Within the openings are shafts 2O each carrying a druin 21, to receive an endless belt 22.` A l The belt 22 is provided at uniformly spaced intervals with carrier bars orslats preiferablyott. bars ais-shown. y y By this ineans 'an eiiectual carrier device is produced whereby the straw or other Ainakterial will be' ted toward the rear end ofthe receptacle when' the druins are actuated.

The rear end 13 ot .the receptacle is formed ywith a relatively large openingiat its jlower pa-rt, andinounted opposite tothis larger opening is ashai't 2d carryingalfdruni Q5, the latter having a plurality radial spikes or teeth 26. One of the rear wheels 15 is provided With a'c'lutch nieniher '27V and the axle 11i is provided With an opposing clutch meii'iher 26 slidable on the aizlezand caused to rotate therewith, for instance .by the Welli known enacting` keyway andkey.

A chain LWheel. 29 .is inouiitedon; the axle 1d and rotates therewith,while a chainpinion 30 is carried by the shaft Q4', and endless chain 31 leading over the Wheel 29 and pinion 30. 'By ythisfineans there:` carrier wheel15 to which the clutch nien Jer 27 ,is

attached, .may he coupled to or iincoupled liroin the'z rear axle bmi/'f niereljgfY actuating` a shipper rod not shown, as'ii'ill heobirious. "llie clutch carrying rear Wheel 15 nia-y thus be `utilized to ztransinit motion tothe toothed drum 25 in the direction o't thearrow, or` dis-` connected therefrom when required. 'y

f The clutch device the chain wl'ieel's-QS) and 30 and the chain 31 areall,arranged eztterf iially o'ithe receptacle, :is shown'. f Attached to one ofthe sidewalle il ol the recoiitacle :is a stubslial p v the stub shaft is u geaii wheel 3?) which engageswith pinion 34 on the axle ifi. y Mounted :for rotatioii through the side wallsl11 olt'the receptacle is another shaft 37 tarrying a druin B8 having radial teeth 39, the drum and teeth` serving` as e beater77 in coaction With niaindruin 25 and its teeth 26. Theshafts 20, 32 and 37 Vareprovided with chain pinions 40, d1 and "LiQfover .which an endless cha-hiel operates, the shafted( heilig carrying;` the slatted belt, will be driven from i the shaft .2f-t.

h/lounted to swing at elfi 'trom the inner tace oit the rear wall 13' ot the receptacle is ya combined guard and controlling device comprising` a plurality ot slats or arms uniformly spaced and curving` from end to end and extending downwardly between the drums and 38, the arms beine; so spaced asto avoid the teeth Q6 and 39 of the drums.

Mounted tor oscillation upon the inner face of themember 13 of the receptacle is a shaft --G carrying a lever arm it?, and extending' vover the rear of the. arms l5 and pivoted to each, is rod e8. Mounted for oscillation upon the rear wall 13 of the receptacle is another shaft t9 and pivoted rcspectively to each other and to the shafts 48 and 49 are toggle links y50, one set of the links being coupled by a rod 51 to the arm 47 of the shaft 26. Attached to the shaft 46 externally of the receptacle is an arm 52 .from which an operating` rod 53 leads. At

vstraw which hask been deposited. in the receptacle is relativelydong, tough. and unbroken, the guards will be adjusted to cause the teeth 26 to project a relatively short distance, in advance oit the guards, and when the straw is short and brittle. the guards will be adjusted to cause the teeth to project Jfor a `great distance. i

Thus the speed ot the feed may he easily controlled by merely adjusting), the location of the `guard with reference to the toothed drums.

, It is easier 'for the teeth 39 ot the beater drum 33 to engage longtough straw when the `uard is adjusted to hold the straw relatively near` the heater drum. hence the neces- Y si tv ilioradjustinig` the guards as above noted.

As the `vehicle is moved. over the field the` aprou7 or `slatted belt 22 and the toothed drums are rotated by the action ot the rear wheel l5 with which the clutch is associated,

andthe contents ot the receptacle fed to the discharging mechanism. The material caughtand picked up from the carrier device bythe teeth of the beater drum and ted thereover and to the teeth of the main drum and thus rapidly :ted downwardly upon the,

By this maniera `ground beneath the rear axle, and is thus prevented trom comingv in contact with the wind and driven thereby over the field.

lt will be noted that the floor 10 and apron 22e-23 travel relatively close to the ground. hence the drums 25 and 38 also travel close to the ground and the latter arranged "in position to rtoed the straw downwardly upon the ground. lt will he noted that the dischargingdrum 25 travels at a higher speed than the feeder drum The apparatus is simple in construction, can be inexpensively manufactured, and operates etlectually for the purposes described.

rEhe preferred embodiment ot the invention is disclosed in the drawings and set forth in the specifications, but it will be understood that any modifications within the scope of the claims may be made in the construction without departing from the principle of the invention or sacrilicing any otl its advantages.,

What is claimed is l. In an apparatus of the class described, a carrier for the material, a ydrum having` radiating` teeth and spaced yfrom the discharge end of the carrier, means Jfor rotat` ing said drum to Lcause its teeth to move downwardly toward the carrier, at the side next to the saine, a toothed picker and feeder drum rotating;A relatively close to the drum and to the carrier at its discharge end and picking' the material'ther-efrom and feeding -t to the downwardly movingI teeth of the4 drum, a plurality ot slats extending` between -the drum and the combined picker and feeder and between which the teeth ot the drum extend. and means for adjusting the slats to control the distance which the teeth of the drum extend in advance ot the slats.

2. An apparatus ot the class described comprising a receptacle havingan opening at one end, a carrier device having its discharge at the lower end of said opening:y a toothed material di schare-ing drum mounted forlotation and extending1 into the opening. said drum being' spaced from the discharge end of the carrier with the teeth next to the same movable downwardly` a combined vpicker, and feeder drum rotating' relatively close to the carrier atits discharge end to pick the material thore'lrom and 'leed it lo the downwardly moving' teeth ol the drum. a plurality ot slats swingfinply vonnected at oneend to the receptacle and extendin er he tween the lirst i'z'ientioned drum and the coinbined picker and feeder and between which the teeth of the first mentioned drum extend, and means tor adjusting the slats to control the distance whichthe'teeth oit said drum extend in advance of the slats.
